Splicing of precursor messenger (pre-m)RNA is a critical process in eukaryotes in which the non-coding regions, called introns, are removed and coding regions, or exons, are ligated to form a mature mRNA. This process is catalyzed by the spliceosome, a multi-mega Dalton ribonucleoprotein complex assembled from five small nuclear ribonucleoproteins (snRNP) in the form of small nuclear (sn)RNA-protein complexes (U1, U2, U4, U5 and U6) and >100 proteins. snRNA components catalyze the two transesterification reactions while proteins perform critical roles in assembly and rearrangement. U2 and U6 snRNAs are the only snRNAs directly implicated in catalyzing the splicing of pre-mRNA. …

Electronic Theses and Dissertations
The versatility of nuclear magnetic resonance (NMR) spectroscopy is apparent when presented with diverse applications to which it can contribute. Here, NMR is used i) as a screening/ validation tool for a drug discovery program targeting the Phosphatase of Regenerating Liver 3 (PRL3), ii) to characterize the conformational heterogeneity of p53 regulator, Murine Double Minute X (MDMX), and iii) to characterize the solution dynamics of guanosine monophosphate kinase (GMPK). Mounting evidence suggesting roles for PRL3 in oncogenesis and metastasis has catapulted it into prominence as a cancer drug target. Yet, despite significant efforts, there are no PRL3 small molecule inhibitors …

The serine protease thrombin plays important roles in coagulation, anticoagulation, and platelet activation. Thrombin is initially expressed as the inactive zymogen prothrombin (ProT). The final cleaved and activated form of thrombin has mature anion binding exosites (ABEs) and several regulatory loops. Engagement with these exosites helps define the fate of thrombin as a procoagulant or an anticoagulant. Researchers previously reported that zymogen ProT may already bind exosite ligands. Little is known about conformational changes associated with ProT maturation, resultant ligand binding affinities, individual ligand-protein contacts, and long-range communication between thrombin exosites. Protease Activated Receptors (PARs) play critical roles in controlling …
